1.下载

 yum install httpd-devel

yum install sqlite-devel -y

yum install bzip2 bzip2-devel -y

yum install curl-devel  -y

yum install gmp-devel  -y 

yum -y install oniguruma-devel

yum -y install postgresql-devel

yum -y install readline-devel

yum install libxslt-devel - y

由于使用postgrsql数据库，需要用到pdo_pgsql接口，发现一直无法加载，没办法采用php源代码重新安装

wget https://www.php.net/distributions/php-8.1.7.tar.gz    //解压源码包

cd php-8.1.7 .编译 #安装路径在/usr/local/php

./configure \

--prefix=/usr/local/php \

#make &&make install

3.设置环境变量 vi/etc/profile 在末尾追加

#这步不一定要运行，往往已经在PATH中

PATH=$PATH:/usr/local/php/bin

export PATH

#执行生效

source /etc/profile

5.配置php-fpm

cp php.ini-production /etc/php.ini

cp /usr/local/php/etc/php-fpm.conf.default  /usr/local/php/etc/php-fpm.conf

cp /usr/local/php/etc/php-fpm.d/www.conf.default    /usr/local/php/etc/php-fpm.d/www.conf

cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

chmod +x /etc/init.d/php-fpm

6.编辑php-fpm 

error_log = /home/log/php-fpm.log

pid = /home/log/php-fpm.pid
